Stone (pictured) takes over from Manuel Moerbach, who has relocated from London back to New York for family reasons.

Moerbach will continue working with Symphony Technology Group (STG), which owns Onclusive, as a senior adviser.

Before joining Onclusive, Stone was chief strategy officer and board director at fellow STG research advisory firm Escalent.

Other prior roles include chief executive at Grail Insights and Market Strategies, co-founder at insights consultancy Doxus and consultant with companies including Apple, Meta, Google and Cisco.

Onclusive has also named STG operating partner John Ouren as executive chairman of its board.

Ouren has worked at STG for nine years, and has prior experience working at business including MarketTools, SurveyMonkey, McKinsey & Co and AlphaImpactRx. He is also a board member at MRI-Simmons.

JT Treadwell, managing director at STG, said: “Rob is a strong and dynamic leader who has led and grown companies of a variety of sizes, including the integration of complex businesses post-acquisition and their establishment as strong independent brands.

“I’d also like to extend my thanks to Manuel for leading Onclusive through building the foundations of the business and our most recent acquisitions of broadcast and podcast monitoring expert Critical Mention and social media listening platform Digimind.

“We are sorry to see him leaving Onclusive, but we respect his decision to step back and look forward to his continued support in his capacity as a senior adviser to STG.”
